  • Patent number: 10014839
    Abstract: Disclosed herein are methods and systems for intelligent dual-channel volume adjustment. One embodiment takes the form of a dual-watch mobile radio that includes a first receiver, a second receiver, an audio output port, a one-dimensional (1-D) volume control, and a controller programmed to carry out a set of functions. The set of functions includes receiving first and second audio signals from the first and second receivers, respectively, and generating first and second amplified audio signals at least in part by applying first and second signal gains to the first and second audio signals, respectively, as well as outputting the first and second amplified audio signals via the audio output port. The set of functions also includes receiving volume-control commands from the 1-D volume control, and responsively adjusting the first and second signal gains at least in part by applying a gain function to the first and second signal gains.
